(Filling a ticket as discussed in #mythtv)

If a user presses the Live TV jump point while in Live TV, MythTV will exit to the main menu, present a "please wait dialog", then re-enter Live TV several seconds later. Proper UX would be to identify that the user is already in Live TV and either ignore the keypress or display the OSD indicating that they are already in Live TV.

I would expect this may be true of other jump points as well (i.e., listen to music, watch videos, etc.)
